Improve Compatibility with Password Managers (e.g., Bitwarden)

Currently, Solid Security appears to replace the default username input field on the login page. As a result, password managers like Bitwarden no longer recognize the username field correctly, making autofill functionality to not work. This forces users to manually copy and paste their usernames, disrupting the login experience.

Please consider updating the input field—possibly by restoring a standard name attribute like username or user_login—to improve compatibility with password managers.
